You didn't mention what gcc error you got.  You need to give complete 
info about a problem if you want a good answer.

Since this is a very target dependent issue, you might try sending mail 
to a cyginw or mingw list.  Gcc developers generally aren't Microsoft 
Windows experts.

I tried a quick web search, it seems the answer is that win32 doesn't 
support direct access to the I/O ports, so you can't do what you are 
trying to do without a device driver.  If you want a better answer, you 
need to ask people who know more about MS Windows programming.
